类方法也分私有和公有方法之分，下面是具体代码
unit Unit2;
interface

TA = class

class procedure aa;
public
class procedure bb;
end;
implementation
class procedure TA.aa;
begin
showmessage('aa');
end;
class procedure TA.bb;
begin
showmessage('bb');
end;
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, Unit2, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
Button2: TButton;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
begin
//
TA.bb; //编译通过
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
TA.aa;//编译通不过
end;
end.
